CLOSURE MEANS FOIR, GAS-RETORTS.

Patented July 6,' 1915..

Application mea February 7,1913. serial No. 746,889.

dTo all whom it may concern Be it known that we, HENRY A. CARPEN-l TER, ROBERT L. HIBBARD, and jCARLE'roN WARREN, citizens of the United States, residing at Sewickley, inthe county of Allegheny and State of Pennsylvania, have invented certain vnew and useful lmprovements in Closure Means for Gas-Retorts, of which the following is a specification.

An object of our invention is to rovide new and improved closure mean or gas retorts.

A further object of the present invention v is to provide improved door operatin mechanism including means for maintaining the door in close Contact with the front face of the mouth-piece of the retort, and means for e'ecting a sliding movement of the door on the mouth-piece Vto-'remove tar and other acportion of a retort mouth-piece with our closure means in plan and applied thereto; Fig. 3 is a side elevational view particularly yshowing the latch mechanism; Fig. 4 kis a .part front view and a part vertical sectional view, the section being taken on line IV-IV of Fig. 2; Fig. 5 is a part side elevational view and a part sectional view, the section being taken on line V-V of Fig. 4 looking in the. direction of the arrows; Fig.- 6 is a horizontal sectional view taken on line vJL-Vl of Fig. 1; Fig. 7 is a planshowing the retort closure means partly open; and

. Fig. 8 is a detailed, perspective View of an eccentric shaft employed. l

Referring tothe drawings, 1 designates an outer portion of a retort bench-wall, and 2 a retort mouth-piece applied thereto.

I s Located 'at one side o and projecting outwardly therefrom, are

the retort mouth-piece brackets 3, which support a hinge-pin 4.

l y Extending transversely across the mouth- 'Y piece, we provide door carrying and door locking means comprising, as illustrated,

two steel forgings or members 5 respectively formed with annularmembers 6 adapted to receive the ends of the hinge pin 4 and bearings therefor. In addition to the' members -the door.

`6, each member k5`is formed with a centrally disposed member 7, and each member 7 is provided with an outwardly projecting bent arm 8. rFhe free ends ofthe members 5 are brought together as clearly shown on the left of Fig. 1, and the opposite ends are se`parated and connected by a bolt 9.

10 indicates the door which is movable with and supported by members 5, the door belng'connected to said members by means I of .the arms 8 and tension springs 11, the

latter connected to the bent extremities of the arms and to lugs 12 formed integral with the door.

Located at the opposite side of the mouthpiece from the hinge pin 4 and supported therefrom by a projecting bracket 13 is a latch mechanism comprising, as illustrated, a latch member proper 14 having apertured bent 'ends movable on parallel rods 15, the latter projecting from pin 16 formed integral with bracket 13. The outer ends of the rods 15 are 'connected byv a member 17, and` interposed between the latter and latch member 14 are therod embracing springs- 18. .When the door is in closed position the free ends of the locking members 5 are engaged bythe spring-pressed latch member 14, Ias in full lines in Fig. 6, and the door is maintained tightly against the mouthpiece.

' Designed to coperate with the parts above described and operable when opening and closing the door are means for relieving the pressure `of springs 18 on members 5, and for ed'ecting a lateral or sliding movement of thev door on the face of the mouth-piece. As illustrated, these means comprise an operating lever 19 carrying an eccentric shaft 20 with the ends thereot mounted in ball bearings 21 in the members' 7,

22 designates the eccentric portion ot the shaft 20, the latter being shown in detail in Fig. 8, the line cp-a' designatestlie center line of the shaft, and line b--b theA center line of the eccentric portion thereof.

rlhe eccentric shaft 20 projects through an annular casing 23 in which is disposed the pull of springs 11.

versal joint, aiording the door such movements relatively to the combined supporting and locking device as to cause the door to tightly engage'all portions of the mouthpiece face under the pressure imparted through shaft 20. The door 10, as particularly shown by Fig. 5, is provided with recesses 27 into which project parts 7 of the door-carrying bars 5 when eccentric shaft .20 is turned by lever 19, as in dottedlines in Fig. 6, to permit said bars to respond to To open the door, lever 19 is thrown from the position shown in full lines in Fig. 6 to the position shown in dotted-lines, thereby rotating'the eccentric shaft, and the resulting inward movement of bars 5 induced by springs-11 frees the extremities bf the bars of pressure from latch springs 18. The latch may then swingA free ofthe door support, releasing the latter for outward or opening movement. After the door has been closed and the latch-swung from the open position of Fig. 7 to that of Fig. 6, movement of lever 19 from the dotted to the full line position of Fig. 6 projects bars 5 away from the door, placing them under theholding and locking tension of latch springs 18.

In addition to movements of bars 5 relatively to the door made effective by shaft 20, the rotation of eccentric portion 22 of the latter in casing 23 results in lateral movement of the door relatively to the mouth-piece, clearing the face of the latter of tarry accumulation and causing the door to close with a gas-tight iit.

In order to prevent the 'operating lever 19 from swinging violently toward `open po- Isition under action of springs 11 after the center line b-b of shaft 20 is out of line with the center line L -a, we provide a spring 28 designed to retard the rotative movement of the eccentricshaft and its lever 19. This spring is secured to members 5 by a yoke 29 and bolt 30, the spring being held forward .under compression with its free end in contact with casing 23, and its l rear end engaging a p in 31 carried by members 5. For *maintaining the door 'l0 parallel with the face of the mouth-piece, we provide registering lugs 32 and 33,*respectively carried by the door and the door carrying members 5.

What we claim is 1. The combination of a retort door, a

- door locking device in front of the door with means for securing said device, springs connecting the door and said device and opposing movement of either of said parts away from the other, and means for effecting such movement-in opposition to the springs.
